In many cultures, the hazel was considered a magical shrub; dowsing rods were traditionally cut from hazel twigs.<\/p>\n<p>Today, around two-thirds of the world&#039;s hazelnut harvest comes from Turkey, primarily from the Black Sea coast; Italy (Piedmont) is known for its aromatic varieties. The hazel is a member of the birch family \u2013 therefore, many people with birch pollen allergies also react to the nut.<\/p>\n<\/section>\n<section class=\"ea-k\" id=\"nutzen\">\n<h2><span>To use<\/span>What the hazelnut does for you<\/h2>\n<p class=\"ea-drop\">Hazelnuts consist of approximately 60 percent fat, predominantly <strong>oleic acid<\/strong> as in olive oil.
